Benefits of technology

The patent text is describing a technology that prevents contamination from external sources from affecting the function of an OLED device. This is accomplished by using a scattering layer or an encapsulation layer that insulates the various layers of the device from external contaminants. The technical effect of this technology is to improve the reliability and lifespan of OLED devices, especially in environments where they may be exposed to various pollutants.

Problems solved by technology

However, as the result of the resonance, the OLED device may suffer from a viewing-angle-dependent color shift.

Embodiment Construction

[0037]Example embodiments of the inventive concepts will now be described more fully with reference to the accompanying drawings, in which example embodiments are shown. Example embodiments of the inventive concepts may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be more thorough and more complete, and will more fully convey the concept of example embodiments to those of ordinary skill in the art. In the drawings, the thicknesses of layers and regions are exaggerated for clarity. Like reference numerals in the drawings denote like elements, and thus their description will be omitted.

[0038]It will be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or directly coupled to the other element or intervening elements may be present. In contrast, when an elemen...

Abstract

An organic light emitting display (OLED) device includes: an insulating substrate; a first electrode on the insulating substrate; a second electrode on the first electrode; a light-emitting layer between the first electrode and the second electrode; a hole common layer between the first electrode and the light-emitting layer; an electron common layer between the second electrode and the light-emitting layer; and a scattering layer on the insulating substrate and having a non-planar surface, wherein the scattering layer includes at least one of benzene, naphthalene, anthracene, tetracene, pentacene, amine, benzidine, biphenyl, carbazole, pyridine, bipyridine, imidazole, phenanthroline, phenylborane, pyrimidine, or triazine, and the base material of the scattering layer includes a substituent including at least one of a benzoyl group, a carboxyl group, an aminophenoxyl group, a tricabonate group, or a styryl group.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This patent application claims priority to and the benefit of Korean Patent Application No. 10-2013-0156528, filed on Dec. 16, 2013, in the Korean Intellectual Property Office, the entire content of which is hereby incorporated by reference.BACKGROUND[0002]1. Field[0003]Aspects of example embodiments of the inventive concept relate to an organic light emitting display device and a fabricating method thereof.[0004]2. Description of the Related Art[0005]Due to its self-luminous property, an organic light emitting display (OLED) apparatus generally does not utilize an additional light source and has the characteristic of enabling electronic products to be relatively small and light compared to electronic devices utilizing other display devices. Further, OLED devices may have relatively lower power consumption, higher brightness, and higher reaction rate compared to other display devices, and thus, OLED devices have received attention as next-...
